Add a wrapper script in the bin directory to make it easier to run extract_msg

[zeroepoch]

Bug Metadata

• Version of extract_msg: 0.27.8
• Your python version: Python 3.9.0
• How did you launch extract_msg?
  • python3 -m extract_msg

Describe the bug
The pip package doesn't install a script in the bin directory (or maybe it doesn't happen on python 3.9 or Fedora for some reason). I have to use python3 -m extract_msg ... in order to run the main script. It would be nice if when installing the wheel file via pip that a wrapper script was installed in the normal bin directory to make it easier to launch. ~/.local/bin is normally added to your PATH for example.

TBH, this isn't a bug: we just never implemented it. I don't actually know how to do that yet, so I guess I have something to look into,

This should work now. The script is simply called "extract_msg". Let me know if you have any problems.

Maybe this is a Windows vs Linux thing, but the script was not executable when installed, so I had to do chmod +x extract_msg. Also it has DOS line endings so it printed the error:

/usr/bin/env: ‘python\r’: No such file or directory

After fixing the executable permissions and line endings it appears to work. Also the stdout option worked great.
